Be it known that we, EDOUARD JOSEPH JEAN BAPTISTE BENOIT, a citizen ofthe French Republic, and J 081 3 SOLER YVILA, asubject of the King ofSpain, both residents of I Paris, France, have invented certain new anduseful Improvements in the Process of and Apparatus for SeparatingOle'ine and Steal-inc from Suet, (for which we have obtained LettersPatent in France, No. 215,639, dated August '21, 1891,) of which thefollowing is adescription.

Our invention relates to a process of and apparatus for extractingorseparating oleine and stearine from suetor rendered tallow formanufacturing purposes, and has for its object to extract or separate ina simple, inexpensive, and expeditious manner the oleine and stearinewithout the use of hydraulic or,

other presses as heretofore.

Our invention consists primarily in the pro cess whereby said separationof the oleine "and stearine may be effected, as hereinafter fullydescribed.

. Our invention also consists in the construction, arrangement andcombination of parts of the apparat-us'whereby our process may becarried out, all as hereinafter fully described, illustrated intheaccompanying drawings and pointed out in the appended claims.

'In said drawings:--Figure lis a sectional elevation of the completeapparatus; Fig.2 a plan view thereof; Fig.3 a detail sectional view ofone of the discharge valves for the' tankv or vat 0. Figs. 4 and 5 are asectional elevation and plan respectively of a slightly different shapeof vat O.

Heretofore in the extraction of oleine and stearine from suet orrendered tallow for manufacturing purposes it has been custom-{ q i C,though desired the number as well as the capacities of these vats may bevaried according to the quantity of material to be treated. The vats A Bare similar in construction and may be ofany suitable material and linedwith sheet nietalp, as shown. Leading into the vat A is a pipe (1, whichat the bottom of said vat is coiled into serpentine form and providedwith a number of fineperforations o. The pipe at, is connecteddetachably to a pipe 0!. by means of a'coupling m, said pipe aleadingoff to a suitable source of steam supply.v A pipe 1), connected.

detachabiy to the. pipe at by coupling a, leadsinto vat Band is coiledinto serpentine form and finely perforated at- 'o. The two vats A, B,communicatewith each other by means of a pipe q, provided with stop-cockZ, while the vats B, C, communicate with each otherby a pipe qprovidedwith stop-cockl'. By means of thepipes a, b, the necessarydegree of heat within the vats A, B, can be obtained by means of thesteam passing through said pipes and the perforations thereof, into thevats where said steam is condensed. and

the water of condensation may be drawn off through cocks It 70 locatednear the bottoms of the vats. i

The vats A, B, C, are supported upon suit able frames or tables A, B, Crespectively,

and the vat A is arranged somewhat higher than vat .B, while the latteris ,somewhat higher than the vatG, whereby the flow of the liquid fromvat A to vat B and from the latter to vat G- will be accelerated.

The pipes q, q communicate with the vats A, B, at points horizontallyabove the cocks A k is so that no water of condensation will be carriedoff or decanted through said pipes q into the vats B, and C,respectively.

The vat O is arranged in a heating chamber G having a constanttemperature of about 30. This vat may be of any suitable material andhas a concave bottom 0' provided with a number of tapering openings 0,in which are adapted to fit the tapering ends of wooden valves d,arranged vertically within the vat 0. Each Valve or rod d, is providedat its lower end with a threaded socket d to receive a screw 71.supported by a bridge a, screwed to the underside of the botchute todeliver the oleine to a suitable ves-' sel placed outside of the chamberG. Aper- IO forated pipe D surrounding the vat O and communicating witha gas supply furnishes canting the same and finally subjecting it to themeans for heating the chamber G.

In Figs. 4 and we show a vat G which has more of a truncated cone shapethan that [5 shown in Fig. 1 the interior of said vat in Figs. 4 and 5being therefore more tapering and more readily permitting the separatedoleine to pass through the openingsc.

In carrying out our process we place the suetortallow to be treated inthevat A where it is heated by the steam passing through the pipe a, andopenings 0, thereof, and liquefies, we then add to the liquefied tallowfrom one percent. to three percent. of pulverized man- 2 5 ganese andpermit the whole to boil for about three-quarters of an hour or an hour,the manganese serving to clarify the tallow, After maintaining thetemperature for aboutfour or five hours and settling we decant or drawoif the liquid matter contained in vat A into.

vat B through pipe q, the extraneous matter or residues being allowed toremain in vat A which may afterward be used for grease. We nowhoil theliquid in vat B for about 5 half-an-hour and then add from two per cent.to five per cent. of cream-of-tartar mixed with a small quantity of hotWater and allow the Whole to est and settle for from three to fourhours. The separation of the oleine and stearine from the soot is acconrplished during this step of the operation.

At the end of this time we ,decant or draw off into vat 0 through pipeq'the separated liquids and allow them to stand for from 5 four to. sixdays according to thetemperature. Owing to the difference in timebetween the ste s of operation performed in vats A, B, an that performedin vat Cwe would employ a suflicient number of vats (J to receive theseparated liquids from vats A, B, during said time of four to six days.We show but one vat 0 however, which is sufficient to illustrate theprinciple of operation. At the end of that time the oleine will hecompletely separated from the stearine; the oleine is then allowed topass through the openings 0, (valves (1, having been raised to permitsaid passage) and falling into the chute E is conducted to a receivingvessel. The oleine hav- 6o ing been discharged the valves d, are loweredto close the openings 0, and the stearine can then be obtained in a moreor less solid state from within the vat O.

What we claim is- 1. The herein described process of separating oleineand stearine from suet or rendered tallow, which consists in liquefyingthe tallow and adding thereto manganese to clarify the same; thenallowing the mass to settle and decanting the non-residuary portion;heating said portion again and adding thereto creamoff-tartar andallowing the mass to settle; del is arranged, means for heatingsaidchamber,

discharge openings and valves in said vat O, and a chute arrangedbeneath the same and adapted to receive the contents of said vat, asdescribed.

3. In an apparatus .of the character described, the combination with thevats A, B, and 0, arranged above one another as .described, andhavingcommunicationwith each other of steam pipesarranged in said vatsA, B, draw-off cocksfor the said vatsA, B, a heating chamber withinwhich said vat 0 is arranged, means forheating said chamber, dischargeopenings and valves in said vat O and a chute arranged beneath the sameand adaptedto receive the contents of said Vat, as described. 7 I

In n pp r of the cha acter described, the combination with the vets A,13, and 0,01. steam. pipesleading into said vats A, B, and communicatingwith a main steam pipe, pipes leading from vat A to vet B and from thelatter to vat C, draw-off cocks for said vats A, 13 located below thelevel of the said connecting pipes where they enter the vats A, B,aheating chamber within which said vat O is arranged, a gas supply pipeleading into said chamber and surrounding the vat O, discharge openingsand valves arranged in the bottom of said vat, anda chute arrangedbeneath said vat and adapted to receive the contents of the same, asdescribed.

In testimony that we claim the foregoing we have hereunto set our handsthis 30th day of March, 1892.
